It really all depends on what you want and need. I hated my TDX3, but really like my TDX5.
I think it was the "True Track". I'm not sure if the TDX3 has it. The TDX3 was just jerky. While driving in a straight line, you know how you make slight corrections? The TDX3 would jerk with each correction. You could feel the motors click and jerk each time. While the TDX5 would smoothly make slight corrections. You could not feel anything. The only thing I saw on the TDX-SP didn't mention True Track. I didn't see the TDX3-4-5 listed on the Invacare site, so maybe they have a new system. I would need/want a faster chair, but some don't. It's a personal preference. But my TDX's have been good chairs. Greg _____ Hi all, I'm due for a new wheelchair & I'm looking at a TDX SP. Any feedback would be helpful. Thanks, Dianna p.s. I do drive with an EZ-LOCK & don't want a recline.
